DISTRIBUTOR BUCKET FOR ROAD BUILDING MATERIALS AND THE LIKE Filed Jan. 8, 1965 J z 5 65,111 3531" w cfea6wmvflm United States Patent 3 Claims. (Cl. 94-46) Hitherto it has been generally assumed that it was impossible to operate the buckets of road building machines without a high weight of the buckets themselves, because otherwise the buckets would be lifted off their guide rails or off the road surface during their forward movement, owing to the high thrust and wearing forces caused by the displacement and distribution of the material. In this case the efiiciency of the drive might be completely eliminated.

The invention is based on the principle of using the material charge of the bucket to a higher degree as the required weight, and to design the bucket itself so that it is lighter, that is to say, so that material may be saved.

According to one feature of the invention, the end walls of the bucket, forming usually simultaneously also the stripper edges, and located in the operating directions of the bucket, are inclined inwardly. Since now the excess charge will be pushed up on one or the other end wall during the forward movement of the bucket, and according to the working direction of the same, this material forms an additional load or force component, urging the bucket on to its guide rails or on to the road surface.

Preferably, this effect is supported by a second feature of the invention, according to which there are arranged in the bucket, laterally of the operating direction, bulkheads which may be moved into opposite oblique positions, wherein these oblique positions may be fixed by end stops. This pivotable arrangement of the bulkheads about pivots along their upper edges or located in the side Walls of the bucket has the object of pushingaccording to the operating direction of the bucket-the bulkheads into a position in which additional material is pushed during the forward movement of the bucket also against these bulkheads, creating further forces preventing the bucket from being lifted off the rails or road surface. This effect is obtained in either operating direction by simple dividing walls. The stops for the bulkheads are formed preferably by iron angles, the legs of which not forming the abutments are longer, that is to say, project deeper downwards so that also the stops not used in one or the other direction are effective in the same sense as the slanting bulkheads in that material is pushed on to the long legs, whilst at the same time preventing an accumulation of material on the rearward abutment faces, inclined in the other direction relative to the direction of movement.

The invention will be further described, by way of example, with reference to the accompanying drawing, in which:

FIG. 1 is a longitudinal cross-section of the bucket according to the invention; and

ice

FIG. 2 is a cross-section along the line II in FIG. 1 in the direction of the arrows.

The bucket 1 has inwardly inclined end walls 2, and may be moved by means of wheel assemblies 3 on guide rails. A height adjustment of the wheel assemblies or of the bucket 1 is possible by screw spindles 4. In the bucket, there are bulkheads 5 which are rotatable about pivots 6, whereby the opposite slanting positions are fixed by end stops 7. These stops 7 have legs 7 and 7" of unequal length so that the legs 7", which do not serve as a'butments, project downwards over a longer section than the legs 7. The bucket is provided with a drawbar 8.

During operation of the bucket in the direction shown by the full line arrow, FIG. 1, the bulkheads are in the position shown in full lines. During the forward movement of the bucket, material is pushed on to the slanting bulkheads 5 and on to the equally slanting end wall 2, causing the bucket to be urged downwardly by the weight of the material pushed on to the slanting surfaces. The free abutments 7 are effective in the same way, because also here material is pushed against the legs 7", projecting further downward than the abutment faces 7'. In this way, an accumulation of material on the shorter abutments 7 is prevented.

If the bucket is to be operated in the opposite direction, as indicated by the broken line arrow, the bulkheads 5 are reversed into the position shown by broken lines. In this manner, during operation in the opposite direction, the same operating conditions may be obtained, as described above.

The bucket may be equipped with its own independent drive, or it may be pulled and pushed by means of a drawbar 8.

What I claim is:

'1. A distributing device for road building materials 'and the like, comprising a bucket having end walls and side walls, a plurality of spaced bulkheads provided in the bucket and each rotatable about a pivot in the side Walls of the bucket, and means in the form of stops below the pivots of which there are two spaced from each other for each bulkhead and secured to the inside sides of the bucket.

2. A distributing device according to claim 1, in which each stop has two legs of unequal length arranged at an angle to each other.

3. A distributing device according to claim 1, in which the end walls each have an inclined inwardly directed section.
